YouTube Now Uses HTML5 by Default in-Browser

Five years after starting support for the HTML5 standard, YouTube has dropped Flash Player to use the HTML5 <video> format as its default player in-browser. According to YouTube, the five-year wait was to allow once-experimental HTML5 time to mature. The HTML5 standard is now widely adopted by the best of the web – even Smart TVs are using it – and it allows live broadcast support an improved widescreen aspect view and more.

This could summon the death knell for Adobe’s Flash Player. With the notoriously buggy Flash still reporting vulnerabilities, how long does the player have left?
